Question

the potential difference between the points X and Y in the adjoining diagram will be​

Answer 1

Explanation:

total resistance between three resistor of x and y is = R s = R1 + R2 +R3

= 3 +2 +1 ohm

= 6 ohm

total resistance in the circuit including the R4

i.e R p = 1/6 +1/3

= 3/6 = 1/2 = 0.5 ohm

V = IR

V = 3 * 0.5

= 1.5 V

p.d = 1.5 V
